At least 20 killed by helicopter barrel bomb attack in Syria
Syrian army helicopters are reported to have bombarded the northern rebel-held town of Al-Bab for a second day.
Footage posted online shows the aftermath of attacks with civilians trying to flee fires while others carry the wounded to waiting ambulances.
Twenty people including four women were killed when the improvised barrel bombs were dropped on the market district of the town. The Syrian Observatory for Human Rights said the death toll could rise as many people were seriously wounded in the attack.
It comes just a day after 26 people were killed in a similar assault on the same town by president's forces.
Barrel bombs are oil drums filled with explosives. They are usually rolled out of the back of helicopters and as such are rarely delivered with any accuracy. The bombardment comes at a time of heavy fighting in the country, particularly around Aleppo. More than 100,000 people have been killed in the two-and-a-half year conflict.
